Question

simplify the following expression
-220x^3y^2/44x^10y^9

Answer 1

first deal with terms in x: -220x^3 / 44 x^10 = -5 x^-7
terms in y : y^2 / y^ 9 = y ^ -7

= -5 x^-7 / y^-7
= = - y^7 / 5 x^7

Answer 2

can you help me with this one?

Answer 3

yes

Answer 4

lol the one i just done or anothter

Answer 5

hmm its not one of my choices

Answer 6

-220x^3 / 44 x^10 = -5/ x^7
y^2 / y^ 9 =1/y^7

multiplying:
= -5 /x^7y^7

Answer 15

no -its number 2!! -5

Answer 16

lol ok:)

Answer 17

got there in the end - maybe i should turn in!!
